Knick achieves a significant increase in reliability and lifetime by developing signal conditioners with extremely low power consumption and self-heating. This leads to a significant increase in the reliability and service life of the electronic components – for example, the MTBF (mean time between failures) of the new VariTrans A 21000 signal conditioners is 280 years. Thanks to the VariPower power supply for all common supply voltages from 24 to 110 V DC (± 25 %) and 110 to 230 V AC (± 10 %), the devices can be used internationally with virtually all supply voltages.
